1) Energy from the sun powers photosynthesis in plants and algae, producing carbohydrates that form the base of most ecosystems' food chains.
2) Some deep sea ecosystems use chemosynthetic bacteria that derive energy from sulfur compounds rather than the sun, as the base of their food chains.
3) Energy is transferred between organisms as one eats another, but about 90% is lost as heat or waste at each transfer, making long food chains unsustainable in most ecosystems.
Tardigrade research
Tardigrades, also known as water bears, are microscopic animals that can survive extreme conditions such as decades in a freezer, rapid dehydration, high temperatures, radiation, and even space. They have the ability to lose DNA to trigger cells to consume themselves for protection, and over time have evolved new protective genes and proteins to preserve their DNA under stress. Scientists have introduced tardigrade proteins into human cells, finding the cells could then better withstand radiation and oxidative stress compared to unmodified cells.
Introduction to Microbial Diversity
Introduction to Microbial DiversityNational Institute of Biotechnology and Genetic Engineering (NIBGE), Faisalabad, Pakistan
Microorganisms come in many forms and play a variety of roles. They can decompose waste, perform photosynthesis, and produce useful products like ethanol and medicines. Microbes also include disease-causing pathogens. There is great diversity among microbes including viruses, bacteria, archaea, fungi, algae, and protozoa. Carl Woese's three domain system classifies life based on cellular organization into Bacteria, Archaea, and Eukarya which includes protists, fungi, plants and animals. Microbes vary in size and shape and inhabit diverse environments.Biotic Interactions
- Biotic interactions include predator-prey relationships, plant-herbivore relationships, competition, and symbiosis. Abiotic interactions involve interactions between organisms and environmental factors like temperature, light, and nutrients.
- Density-dependent factors like predation and competition cause populations to decrease when densities are high and increase when densities are low. Density-independent factors like fires and floods impact populations independently of their densities.
- Predator-prey relationships can follow stable, cyclical, erratic, or extinction patterns depending on factors like carrying capacity and reproduction rates of both species. Predators benefit from food while prey benefit from reduced competition.

Biodiversity
Biodiversity refers to the variety of all living organisms, their genetic information, and the ecosystems they inhabit. There are three levels of biodiversity: genetic diversity within and among species, species diversity or the number of different species, and ecosystem diversity which is the variety of habitats and ecological communities. While over 1.4 million species have been described, the total number of species on Earth is estimated to be between 5 to 80 million. Maintaining genetic diversity within populations and species is important for their ability to adapt to environmental changes.
Energy flow in ecosystems
- Sunlight provides energy for most life on Earth through the process of photosynthesis, where plants, algae, and some bacteria use carbon dioxide, water, and sunlight to produce sugar and oxygen.
- Producers are organisms that convert sunlight into chemical energy through photosynthesis. Consumers eat other organisms for energy and include herbivores, carnivores, and omnivores. Decomposers and detritivores break down dead organic matter.
- Cellular respiration is the process where cells use sugar and oxygen to produce energy, carbon dioxide, and water. Energy transfers between organisms as they eat each other in food chains and food webs.
Organism and Its Environment
This document discusses various concepts related to how organisms adapt to their environments, including adaptation, evolution, natural selection, ecological niches, and species interactions. It defines key terms like adaptation, evolution, Darwin's theory of evolution, mechanisms of evolution, ecological niche, niche types, speciation, extinction, and organism interactions. Examples are provided to illustrate concepts like natural selection, genetic drift, mutation, migration, microevolution vs macroevolution, fundamental vs realized niche, and speciation patterns. Factors that can influence speciation and extinction like continental drift, climate change, and catastrophic events are also outlined.
Day 22 december 2 chapter 15
This document summarizes key concepts from Chapter 15 of an ecology textbook, including:
1) Natural selection causes organisms to become adapted to both biotic and abiotic environmental factors. Each species' niche defines its role in a community.
2) Competition and predation are important influences on community structure. Predation produces adaptations in both predators and prey.
3) Not all species interactions are negative - mutualism and commensalism are examples of positive interactions. Communities can change over time through succession or remain stable.

HEE Chapter 5
This document summarizes key ecological concepts including:
1) The study of ecology examines interactions between organisms and their environments. Environments provide living (biotic) and non-living (abiotic) factors that affect organisms.
2) Organisms have niches defined by their habitat needs and roles. Populations evolve through natural selection acting on genetic variation between individuals.
3) Organisms interact through predation, competition, and symbiotic relationships like parasitism, commensalism, and mutualism.
4) Energy and nutrients cycle through ecosystems, with producers, consumers, and decomposers playing important roles in food chains, webs, and biogeochemical cycles.
Climate change increases risk of death caused by new microbes
A graduate of Middlesex School, Matthew Kafker received various awards during his high school years for his outstanding academic performance. In addition to English, Matt Kafker speaks Spanish and French. In 2016, he was named the Outstanding Senior in French by the American Association of Teachers of French. Matt Kafker is now a university student performing research in microbial ecology.
Microbial ecology is the branch of science that studies the relationships between microbes in the environment and their interaction with each other. Recently, professors from the Johns Hopkins University School of Medicine said that the continuing climate change may unlock new microbes that are dangerous to humans.
Microbes can adapt to high temperatures and defeat the human body’s endothermy defenses, which leads to infectious diseases. Endothermy allows warm-blooded mammals, including humans, to maintain temperature to protect the body from infectious diseases and preventing the activity of dangerous microbes.
Previous examinations of global climate change have cited the tropical and subtropical regions to be at a greater risk of high-temperature-related illnesses and deaths. The United States and Europe can also expect increases in heat-related illnesses and deaths.
2016 Raab et al.
This study analyzed bed bugs collected over one year from a lower-income apartment building with recurring infestations after heat treatments. Genetic analysis found that 73% of infestations were from the same lineages, indicating heat treatments were ineffective at eliminating populations. Up to 5 infestations represented new introductions. High levels of pyrethroid resistance were also found. The researchers concluded ineffective heat treatments, new introductions, reintroductions, local spread, and high pyrethroid resistance caused chronic infestations.
Population dynamics
Population dynamics refers to how populations change over time. A population is a group of the same species occupying an area for a period. Population characteristics include density, spatial distribution, range, and reproduction patterns. Density-independent factors like weather affect populations regardless of size, while density-dependent factors like disease depend on population number. Birth rate, death rate, immigration, and emigration influence population change. Ecosystem stability relies on resistance to environmental changes and resilience in regaining function after disturbance. Species richness and keystone species promote stability.
Biology 1 Unit 3 notes
This document summarizes key concepts about ecosystems, including:
1) Ecology studies interactions between living things and their environment at different levels of organization, from organisms to ecosystems. Biotic factors are living parts of the environment like plants and animals, while abiotic factors are non-living like sunlight, temperature, and wind.
2) Energy enters ecosystems through producers, mostly plants that use photosynthesis, and flows through food chains of consumers like herbivores, carnivores, and decomposers. Only about 10% of energy is transferred at each trophic level with 90% lost as heat.
3) Matter cycles through ecosystems in biogeochemical cycles like the water, carbon, and nitrogen cycles which move
Amphibian Die Off
The chytrid fungus Batrachochytrium dendrobatidis (Bd) is responsible for the infectious disease chytridiomycosis that is devastating amphibian populations worldwide. Bd was first discovered in Australia in 1998 and has since spread globally, causing population declines and extinctions of over 200 frog species. While the exact origin of Bd is unknown, it likely spread through increased global trade and transport of amphibians. Climate change may also be facilitating the spread and emergence of Bd in new areas by forcing amphibians to higher elevations and latitudes. Conservation efforts include capturing wild amphibians, breeding them in chytrid-free environments, and re-releasing them to help

introduction to biology .chapter 1 (1st year )
This document introduces important branches of biology such as environmental biology, microbiology, marine biology, parasitology, human biology, and social biology. It discusses biological organization from the atomic level to populations and communities. Examples are given of theories in biology like the evolution of the giraffe's long neck. The document also outlines how biology benefits mankind through food production, disease treatment, conservation, and various techniques like transgenic organisms, selective breeding, cloning, tissue culture, and biological control.
Chapter 13: Species Interaction, Population Dynamics and Natural Selection
This chapter discusses species interactions, population dynamics, and natural selection. It covers different types of species interactions where one population influences another by competing for limited resources. This can affect the birth and death rates of both populations and influence their dynamics over time. Phenotypic differences within populations can result in varying degrees of interaction and natural selection. Coevolution is the reciprocal evolutionary change that can occur between two species through beneficial or detrimental interactions. Adaptive radiation and niche differentiation can also result from biotic interactions that create selective pressures leading to phenotypic and genetic divergence between populations.
Biodiversity
This document discusses biodiversity and its impacts on the environment. It defines biodiversity as the variety of life on Earth, including three main types: species diversity, genetic diversity, and ecosystem diversity. The document outlines several important roles of biodiversity, such as providing food and medicine. However, biodiversity faces threats like habitat loss, pollution, and climate change. Preserving biodiversity requires actions like creating wildlife reserves and breeding programs. The document also defines the environment and its components, noting that all living things depend on the environment for survival. Environmental challenges include issues like population growth, poverty, and pollution.
Ch20
This document discusses strategies used by living things to acquire and use matter and energy. It covers the organization of life from the biosphere level down to cells and molecules. Key strategies discussed include how fungi grow as filaments and decompose matter, how plants obtain water and nutrients through roots and photosynthesis, and how animals have diverse phyla and body structures suited to different environments and modes of survival. The document stresses that all living things face the basic tasks of obtaining and distributing energy molecules while reproducing.
Grade 9, U3-L3 Food Chains and Food Webs
This document discusses ecological niches, food webs, and ecological pyramids. It defines key concepts like producers, consumers, herbivores, carnivores, omnivores, and describes trophic levels. Food chains are simplified representations of feeding relationships, while food webs show complex and interconnected feeding relationships in an ecosystem. Ecological pyramids illustrate the transfer of energy and biomass between trophic levels, with higher levels containing less energy and fewer individuals than lower levels due to energy loss at each transfer.
Basics of cell culture
cell culture define as removal of cells from an animal or plant and their subsequent growth in a favorable artificial environment.
Today, it has large prospective, Used in cellular and molecular biology
Studying the normal physiology and biochemistry of cells(e.g., metabolic studies, aging)
Used in drug screening and development and large scale manufacturing of biological compounds (e.g., vaccines, therapeutic proteins) etc.
Bacterial Physiology and genetics
Bacterial physiology and genetics can be summarized as follows:
1. Bacterial physiology refers to the biochemical reactions that enable bacteria to live, grow and reproduce. Important factors for bacterial growth include nutrients, temperature, pH, and oxygen requirements.
2. Bacteria grow through a lag phase, log phase, stationary phase, and death phase. The log phase is when rapid, exponential growth occurs through binary fission.
3. Bacterial genetics involves the study of heredity and variation in bacteria. Genetic information is contained in bacterial chromosomes and plasmids, and can be transferred between bacteria through transformation, transduction, and conjugation.
Day1
Biology is the study of life. There are several key characteristics of living things including being made of cells, able to reproduce, and having genetic material in the form of DNA or RNA. DNA contains the genetic code and is able to self-replicate to allow for the survival of organisms. There are several themes that unite biology including cells, heritable genetic information, emergent properties from component interactions, and regulation through feedback mechanisms. Organisms are classified into domains, and evolution occurs through natural selection of heritable traits that increase reproductive success.

Lect 2 Microbial Growth.ppt
Microbial growth and temperature conditions are summarized. There are five main groups of microbes based on optimal temperature: psychrophiles, psychrotrophs, mesophiles, thermophiles, and hyperthermophiles. Bacteria primarily reproduce through binary fission, though some species bud. The bacterial growth curve consists of four phases: lag phase, exponential/log phase, stationary phase, and death phase. A variety of physical and chemical methods are used to control microbial growth, including heat, radiation, filtration, chemicals, and food preservatives.

Bacteria are microscopic single-celled organisms that can cause disease in humans. They come in different shapes (coccus, bacillus, spirillum) and are classified by their cell structure and staining (Gram-positive, Gram-negative). Bacteria reproduce through binary fission and conjugation. Many diseases are caused by pathogenic bacteria, such as strep throat, tuberculosis, cholera, and tetanus. Antibiotics can treat bacterial infections by inhibiting bacterial cell wall synthesis or protein/DNA synthesis. Vaccines work by exposing the immune system to killed or weakened bacteria to develop immunity against disease. Proper cooking, sanitization, and antibiotics control bacterial growth and spread of disease.
Physico-chemical Factors That Influence the Environmental Fate of Microbes
The document discusses various physico-chemical factors that influence the environmental fate of microbes, including temperature, radiation, pH, oxygen, solute concentration, and water activity. It classifies microbes based on their optimal ranges for these factors, such as psychrophiles for temperature, acidophiles for pH, and halophiles for solute concentration. The document explains how these factors affect microbial growth, metabolism, and membrane properties.
Factors affecting the growth of microbes
This document discusses the physical factors that influence the growth of microorganisms, including temperature, pH, osmotic pressure, hydrostatic pressure, and radiation. It describes how each factor affects microbial growth and membranes. Temperature is the most important physical factor, as it can damage enzymes and membranes at extremes. Microbes are classified based on their optimal temperature ranges, such as psychrophiles, mesophiles, thermophiles, and hyperthermophiles. Optimal pH and osmotic pressure ranges also determine bacterial classifications like acidophiles, alkalophiles, halophiles, and osmotolerant microbes. Higher hydrostatic pressures and radiation can also impact microbial growth.
Control-of-the-Microbial-Growth.ppt
Control of microbial growth is important in medicine, food production, and other areas. Historically, methods like salting, smoking, and drying foods helped control spoilage. In the 1800s, Semmelweis and Lister developed aseptic techniques to prevent surgical infections. Sterilization kills all microbes while disinfection reduces pathogens. Physical methods to control microbes include heat, filtration, radiation, and dessication. Chemical disinfectants include phenols, halogens, alcohols, heavy metals, quaternary ammonium compounds, aldehydes, and gaseous sterilizers. Proper application of these physical and chemical methods is key to preventing contamination and disease.

Tho control of microbial growth
This document discusses various methods for microbial control, including sterilization and disinfection. Sterilization completely destroys all microbes, including endospores, often through heating methods like steam or ethylene oxide. Disinfection reduces microbes but may not kill endospores, using physical or chemical techniques on living tissues or surfaces. Antimicrobials are selected based on their intended use and whether they kill microbes or just inhibit growth. The effectiveness of control methods depends on factors like the initial microbial load, environment, and exposure time. Membrane damage and interference with cellular functions are common modes of action.

It begins by defining microbiology as the study of microorganisms, which are living things too small to see with the naked eye and include bacteria, fungi, protists, and viruses. It then discusses the importance of microorganisms in areas like medicine, nutrient recycling, and food production. The document proceeds to classify the major types of microbes like archaebacteria, eubacteria, and fungi. It describes bacterial structure, shapes, arrangements and differences between gram-positive and gram-negative bacteria. Key fungal traits and examples are also outlined. The summary concludes with a high-level overview of microbiology techniques.
Physical factors that influence microbial growth
Physical factors, such as temperature, pH, and oxygen levels, strongly influence microbial growth. Temperature is especially important, as it can damage microbes and disrupt cell membranes at extremes. Bacteria are typically classified by their optimal temperature ranges as psychrophiles, mesophiles, thermophiles, or hyperthermophiles. pH also affects microbial growth, with bacteria generally preferring neutral pH levels between 5.5-8. Osmotic pressure and hydrostatic pressure influence whether bacteria can survive in certain environments. Radiation such as sunlight can also impact microbial growth and mutation rates.
Biotechnology
Biotechnology uses cellular and molecular processes from fields like genetics, microbiology, and molecular biology to develop technologies. It harnesses aspects of nature to create products that improve lives and health. Examples include applications in medicine, agriculture, environment, and food processing. Biotechnologies are created by inserting DNA from one organism into another or modifying DNA to produce a desired trait. Herman the Bull was the first farm animal engineered with a human gene for lactoferrin to potentially produce human milk proteins, but he died at age 13 of arthritis. Genetically modified organisms (GMOs) aim to increase yields and profits but also carry risks like allergens, harm to wildlife, and unintended environmental effects.
Biology introduction
This document provides an overview of key concepts in biology, including the characteristics of life, levels of biological organization, scientific classification, and the scientific method. It discusses that all living things share characteristics like organization, metabolism, growth, response to stimuli, reproduction, and homeostasis. It also summarizes the hierarchical classification system used in biology and outlines the domains, kingdoms, and scientific naming conventions. Finally, it briefly introduces concepts like ecosystems, biodiversity, and the process of scientific inquiry.

The goal of the course is to understand microbes'
Physicalgrowth control
The document discusses various methods for controlling microbial growth, including both physical and chemical methods. Early civilizations used techniques like salting, smoking and drying foods to prevent spoilage. In the mid-1800s, Semmelweiss and Lister helped develop aseptic techniques to prevent surgical infections. The document defines terms like sterilization, disinfection, antisepsis and provides details on methods such as heat, filtration, radiation, dessication and chemical disinfectants. It discusses factors that influence the effectiveness of various antimicrobial treatments.
APES Ch. 3, part 1
This document provides an overview of key concepts in ecology, including the levels of biological organization, types of cells, trophic levels, energy flow through ecosystems, and nutrient cycling. It defines important terms like population, community, ecosystem, biosphere, producers, consumers, decomposers, food chains, and food webs. It also explains how energy is lost at each trophic level and illustrates this through energy and pyramid diagrams.

The document discusses the history of the Lake Arrowhead Microbial Genomes (LAMG) conference. It reveals that LAMG2020 was cancelled due to a secret plan by organizers who formed an "anti-karyote society" that hates eukaryotes. The meeting was to be renamed the "Big, Large, Enormous" meeting of the Lake Arrowhead Big Large Enormous Anti-Karyote Society. The document also hints that several past LAMG speakers have made cryptic comments indicating involvement in a conspiracy surrounding the conference.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
